Take a look at this website and answer each of the following questions as you read through the site.
Question 1
1.

__________ is the difference in charge between two points.

Question 2
2.

_____________ is the rate at which charge is flowing.

Question 3
3.

_____________is a material's tendency to resist the flow of charge.

Question 4
4.

A circuit is a _____________ loop that allows charge to move from one place to another.

Question 5
5.

The amount of potential energy between two points or the difference in charge between the two points is called _____________.

Question 6
6.

_____________ is the amount of charge flowing through the circuit over a period of time.

Question 7
7.

Current is measured in __________. (Full word)

Question 8
8.

What is the unit for describing the amount of resistance in a circuit? (Full word)

Question 9
9.

1 V = 2 A * 2 Ω

Question 10
10.

What is the keyboard shortcut used to get Ω?

I'll give you a hint. It begins with ALT+??? What's the number?

Question 11
11.

Example - Power is an electrical quantity and it is represented in equations using the letter P. It's base unit is Watts and is represented after quantities with W. I can describe the power a lightbulb uses as P = 40 W.

Match the electrical quantity (voltage, current, resistance) with its base unit symbol (what you put after a number:

Question 13
13.

What should should happen to current in a circuit if voltage remains the same and resistance increases?

Question 14
14.

What should a circuit designer do to make an LED brighter in a circuit while keeping the same total voltage in the circuit?

Question 15
15.

You must place a resistor in before an LED in order to control the amount of current going to the LED. Putting a resistor after the LED will have no impact and will cause the LED to burnout.
